Best Airline-Approved Pet Carriers

dog in airline approved carrier

We’ve chosen our top picks for airline pet carriers based on several factors, including quality and durability, good ventilation and other pet comfort features, safety features, carrying ease, pricing, customer feedback, and more.

All of the best dog carriers for airplanes we review here are for in-cabin use, except for our top pick for the cargo area for large dogs. All carriers must be small enough to fit completely (and comfortably) in the seat in front of you with plenty of ventilation for your pet (without them remaining inside and closed at all times).

Here are the recommended size requirements for the major U.S. Airlines:

This Sherpa dog carrier for a plane is one of the most popular in-cabin airline-approved dog carriers for its fantastic features, reasonable price, and the company’s unique Guaranteed On-Board program.

If you want to give your pup a bit more room to stretch out in the airport or during your flight, this Petsfit Expandable Pet Carrier is a must. Its wire frame and durable oxford cloth material keep it from collapsing, but it compresses well under the seat. It features anti-scratch mesh ventilation, two-way access, cozy padding, self-locking zippers, and a storage pocket. You can attach it to your rolling luggage or use the hand or shoulder straps.

According to customers, the small and medium sizes are airline-approved, but the large may be too high to meet some airlines’ requirements. However, Petsfit says you can remove two detachable fiber optic rods at the top to decrease the bag’s height.

Most Stylish: Wild One Pet Carrier Review

Wild One Travel Carrier

Visit Website

Looking for the best airline pet carrier that’s also stylish? The Wild One carrier has all the bells and whistles you’d expect, plus a comfy plush mat to lay on. The top zipper moves in either direction, and both sides open up, giving you flexibility. There is no window on the sides, but there is a full mesh area for the dog to see and breathe easily. There are plenty of zipper pockets to store treats and other items, including a slot for your phone case on the side. The carrier has a padded strap to carry on your shoulder (which doubles as a leash!) and sturdy handles if you prefer to hold it in your hands. 


Our First-Hand Experience

cavalier in wild one dog carrier for air travel

“Our 15-pound dog has plenty of room and seems very cozy inside. He likes being able to pop his head out of the corner to look around. The high-quality material makes it durable and easy to clean. The padding on the bottom is spongy and supportive, almost like an orthopedic bed. It has all the strength of a heavy-duty carrier at a lighter weight than the average, making it easier to carry.”

Sadie Cornelius, parent to Cavalier King Charles Spaniel

Best For Large Dogs: Petmate Sky Kennel Pet Carrier Review

Petmate pet carrier

View on Amazon

This Petmate airline-approved pet carrier for large and extra-large dogs meets the requirements for pets flying in the cargo area — although some airlines may require extra metal bolts, which Petmate sells separately in its travel kit. With heavy-duty, durable construction, this TSA-approved pet carrier will keep your pup safe and comfortable.

It’s ventilated on all sides and comes with a clip-on food and water bowl, two “Live Animal” stickers, and pet ID stickers. It also has convenient pre-drilled zip tie holes (airlines require you to zip tie the kennel door shut). Just be sure to check with your airline about the size and weight restrictions when flying with larger dogs.

Note: Most major U.S. airlines do not allow pets to fly in the cargo area anymore due to liability reasons. There is no temperature control, and air cabin pressure is a risk (in addition to pets not being supervised in transit). If you are moving or need to travel long distances, we recommend working with a pet relocation service.


Heavy-duty constructionMetal bolts, zip ties, and pet bed sold separately
4-way vault door for extra securitySome reports that the kennel sizing is off
Includes clip-on food and water bowls
Available in 6 sizes
Made in the USA
